Lisière forestière de la savane de Kandara (30 km au sud de Bertoua, Cameroun). On note la présence d'un fourré de Chromolaena odorata et de termitières-champignons, visible au premier plan de cette savane herbeuse. L'étude de la composition isotopique du sol des zones de contact forêt/savane au Cameroun, a permis de conclure sur une avancée probable de la forêt tropicale sur la savane. Ce phénomène pourrait très bien avoir un impact sur l'évolution des teneurs en dioxyde de carbone de l'atmosphère.
